Republican debate highlights and analysis: Candidates squabble in Simi Valley

DeSantis is dodging the facts.

The Florida Board of Education set new social studies standards for middle schoolers July 19.

In a section about the duties and trades performed by enslaved people, the state adopted a clarification that said "instruction includes how slaves developed skills which, in some instances, could be applied for their personal benefit."

Experts on Black history said that such language is factually misleading and offensive.

Marvin Dunn, a psychology professor emeritus at Florida International University, has authored several books on the history of African Americans.

"Most enslaved people had no special skills at all that benefited them following their enslavement," Dunn said. "For almost all their skill was picking cotton. An enslaved man who was made to be a blacksmith might have been a king had he not been captured and taken from his country. Is he supposed to be grateful? Enslavement prevented people from becoming who and what they might have been and that was slavery's greatest injury to humankind."

Bruce Levine, an emeritus professor of history at the University of Illinois and author of "Half Slave & Half Free: The Roots of Civil War," was one of several scholars of the period who told PolitiFact that they rejected the value of spotlighting "skills" learned while enslaved.

"Very simply, can you imagine saying this about ‘skills’ developed in Nazi forced-labor camps?"

Several of the Republicans on stage touted their prioritization of border security should they win the presidency.

“What I’ll do on day one is sign an executive order to send the National Guard to partner with Customs and Border Patrol to make sure that we stop the flow of fentanyl over the border,” Christie said first. He expanded his answer to include his plans to fill the “6 million vacant jobs” in the country with legal immigrants.

“This border is going to be a day one issue for me as president,” DeSantis said, also noting that he’d administer the remain in Mexico policy, which requires migrants seeking asylum to remain in Mexico until their US immigration court date.

“We're going to declare a national emergency. Yes, we'll build the wall. We’ll do remain in Mexico,” DeSantis said.

Pence spoke about his role in negotiating the remain in Mexico policy of the Trump administration.

“I negotiated the remain in Mexico policy with the Mexican government. We used economic power to bring the Mexican government to the table. We build hundreds of miles of border wall and despite what's said here today, we reduced illegal immigration and asylum abuse by 90%. And as President of the United States, I can do it again,” he said. “I'm going to be ready on day one to get Congress to step up, secure the southern border of the United States.”

Haley cosigned on the Remain in Mexico Policy.

“Let's go back to Remain in Mexico policy,” she said. “Instead of catch and release. Let's go to catch and deport.”
Ramaswamy said that he was supportive of most of his opponents’ border positions, but that he’d go a step further: he’d end birthright citizenship for the kids of illegal immigrants.

“The Republicans on the stage are on the right side of this issue, militarize the southern border, stop funding sanctuary cities and end foreign aid to Mexico and Central America to end the incentives to come across,” Ramaswamy said.

Trump isn’t at the debate, but he’s very clearly on candidates’ minds, with the former president getting direct attacks from Christie, DeSantis, and others for not being present. (Christie’s unforgettable line: “You’re ducking these things... We’re going to call you Donald Duck.”)

But with the opening of the debate so focused on labor and the autoworkers strike, Trump’s campaign is using that ducking as a bragging point, boasting about the fact that Trump is the only one out with autoworkers tonight.

"Amazing that the first question of the debate is about the UAW strike …at this moment where is @realDonaldTrump? He’s in Michigan …talking to striking workers," senior Trump campaign adviser Chris LaCivita wrote on X.

However, as ABC News has previously reported, the place Trump spoke at tonight is one of the few non-union auto-parts plants in Michigan, according to AFL-CIO, and very few of those who came to see Trump in Clinton Township, Michigan, Wednesday evening that ABC News spoke with were on actually on strike.

There are a lot of factors at play over this: Trump’s power in being part of the debate narrative while absent, ongoing labor strikes, and where Republicans show solidarity with labor (and the optics of how they do so). And then candidates like Christie add some nicknames to the mix.

Ramaswamy was asked about whether parents have the right to know about children’s identification in schools. According to a Selzer & Co./Grinnell College poll conducted in March, 71 percent of Republicans say it’s “very important” for a teacher to notify parents if a middle school student has adopted a gender identity different from the one assigned to them at birth.
